Exchanges with USDT and USD pairs on Crypto Auto Trading
What's the difference between USD and USDT pairs?
In most exchanges we use the USDT pairs (like ETH/USDT, BTC/USDT...) to find arbitrage opportunites, but some exchanges do not have Tether (USDT) stable coin available to trade against main crypcorurrencies. In some cases, they simple allow trading between USDT/USD.
The exchanges that just have USD to trade, are those that use USD to place trades against cryptos (ETH/USD, BTC/USD...). In this cases, arbitrage opportunities are calculated against other exchanges using their USDT/USD price in real time. It's why on the Auto Trading platform some exchange show their USDT or USD balance.
Which exchanges use USD?
Kraken, Bitstamp. In the case of Kraken, the USDT/USD pair is available on the exchange, which will be allow us to make the transfer between other echanges.
